12:05 AM miss0r2: mornin
12:08 AM miss0r2 is now known as miss0r
12:08 AM CaptHindsight: oh man is it morning already?
12:08 AM miss0r: somewhere on the planet, it seems :)
12:08 AM roycroft: it is always morning somewhere
12:08 AM roycroft: the sun never sets on the linuxcnc empire
12:08 AM miss0r: lol
12:08 AM CaptHindsight: never rises some days
12:08 AM miss0r: hehe, this was just posted in #electronics : https://xkcd.com/1378/
12:08 AM roycroft: if it never sets it never needs to rise
12:08 AM miss0r: okay, that site is hilarious: https://xkcd.com/730/
12:08 AM roycroft: are you just now discovering xkcd?
12:09 AM roycroft: if so, we'll see you back here in a few hours :)
12:09 AM miss0r: ...yeah..
12:10 AM miss0r: Just when i've decided to be productive for a change.. heh
12:10 AM CaptHindsight: I might be old to find it amusing or insightful
12:10 AM roycroft: i've been reading it daily for many years
12:11 AM miss0r: I used to read hackles.org
12:11 AM miss0r: Then they decided to stop. That was back when I enjoyed web comics. userfriendly was also good.. I think that might still be going
12:18 AM roycroft: xkcd is what dilbert should have been, had dilbert evolved
12:25 AM miss0r: damnit... I am already wasting time here... but I.. Cant.. SOTP!
12:38 AM CaptHindsight: miss0r: what are you working on?
12:39 AM miss0r: Putting the finishing touches on the documentation for the machine i've build and installed
12:41 AM miss0r: I've just decided to put together some photos on imgur, hang on
12:46 AM miss0r: CaptHindsight: This is what it looks like: https://imgur.com/a/KBhR4
12:51 AM roycroft: aah, life is good
12:52 AM roycroft: i just replaced some of the lamps in my pre-amp
12:52 AM miss0r: what pre amp?
12:52 AM roycroft: and it is a beautiful device again
12:52 AM roycroft: mcintosh c28
12:52 AM roycroft: i got some led lamps to replace the incandescent lamps
12:53 AM miss0r: pretty
12:53 AM miss0r: Sadly, the design screams early '80, in my opinion, anyway
12:53 AM roycroft: mcintosh is some of the best stereo gear every made
12:54 AM roycroft: the c28 was made from the early to mid 70s
12:54 AM miss0r: ahead of their time :D
12:54 AM roycroft: but the design is classic
12:54 AM roycroft: my tuner is an mr73
12:54 AM roycroft: it is the last tuner mcintosh made with a vacuum tube
12:54 AM miss0r: I use a NAD series 20 preamp
12:55 AM roycroft: that's a decent preamp
12:55 AM miss0r: I've loon beem thinking of buying a proper tube amplifyer.
12:55 AM CaptHindsight: miss0r: does the cradle hold something that gets wrapped?
12:56 AM roycroft: with all due respect, mcintosh is a lot better
12:56 AM miss0r: I don't believe I will be able to hear the difference, but I would like to have it nontheless. I think it is beautiful :)
12:56 AM CaptHindsight: I'm anti-tube for audio
12:56 AM roycroft: i worked at a high end hifi shop in the '70s
12:56 AM roycroft: i lusted after this gear, but could not afford it until 20 years later
12:57 AM roycroft: my mr73 was rebuilt and recapped by a former mcintosh engineer last year
12:57 AM miss0r: CaptHindsight: it catches silicon wafers as they are cut off
12:57 AM roycroft: my amp is an mc2100
12:57 AM roycroft: i'd like an mc2105
12:57 AM roycroft: which is the same amp, but with a front panel
12:57 AM CaptHindsight: SiO2 wafer catcher
12:57 AM roycroft: and i use stacked advents for my speakers
12:58 AM roycroft: original advents, with walnut cabinets
12:58 AM roycroft: it's a pretty sweet setup
12:58 AM miss0r: I run a pair of infinity cappa speakers
12:58 AM roycroft: but i've been thinking of replacing the speakers with a pair of dahlquist dq10s
12:58 AM CaptHindsight: 6LB6?
01:00 AM roycroft: the mr73 has a 6hu6
01:01 AM roycroft: stereo detector tube
01:01 AM CaptHindsight: https://www.tubedepot.com/t/tubes/power-tubes
01:01 AM CaptHindsight: I haven't looked at them in years
01:01 AM miss0r: It seems theres a few decades between out setups :)
01:01 AM miss0r: All a matter of prefrence i'm sure.
01:01 AM roycroft: yeah, all my gear is vintage 1970s
01:02 AM roycroft: i would guess that there may be a few decades between our ages as well
01:02 AM IchGucksLive: morning from a sunny Germany
01:02 AM roycroft: there is some really good modern hifi gear
01:02 AM roycroft: 'morgen
01:02 AM miss0r: It would seem so. I've come to realize I'm part of the younger generation in here :]
01:02 AM miss0r: morning IchGucksLive
01:03 AM roycroft: there really hasn't been any major improvements in analog audio technology since the '70s
01:03 AM roycroft: tighter manufacturing tolerances
01:03 AM CaptHindsight: IchGucksLive: howdy, the scales I have are mostly OEM versions without the the cables
01:03 AM miss0r: I rarely get to use my setup these days. It pretty much requires the the wife and kid leaves home while i'm at it. Theres no where safe in the house at that point :)
01:03 AM CaptHindsight: IchGucksLive: if they had the cables and connectors it would be easy
01:04 AM roycroft: but i don't think there's anything newer that one can buy that sounds better than the state of the art from the '70s
01:04 AM roycroft: and mcintosh were definitely state of the art
01:04 AM roycroft: there were other equivalent players
01:04 AM roycroft: i'm not saying they were the best
01:05 AM roycroft: but they've always been up there since mcintosh labs were founded in 1949
01:05 AM roycroft: anyway, the front panel of my c28 was fairly dim until a few minutes ago
01:05 AM miss0r: AS with most of these things, When you hit the upper middle class components, you'd need a measuring rig to detect the improvement to the high end stuff. (again, in my opinion)
01:05 AM roycroft: now it has the beautiful green mcintosh glow
01:05 AM miss0r: One must be carefull not to start an audio religion war :D
01:05 AM roycroft: not really
01:05 AM roycroft: i'm not being careful
01:05 AM roycroft: but i'm not interested in a war
01:06 AM roycroft: there's a lot of good gear out there
01:06 AM * miss0r hints at; you never knows who else might be listening in
01:06 AM roycroft: and i do not care and never have cared about specs
01:06 AM roycroft: i care about how it sounds
01:06 AM miss0r: That we can agree on
01:06 AM IchGucksLive: CaptHindsight, if they are suposed to fit the heidenhain they must be the same out
01:06 AM roycroft: back in the day, crown, yamaha professional, and mcintosh were the great ones on the high end
01:07 AM IchGucksLive: CaptHindsight, lee the ls datascheet for pinout inside the scale
01:07 AM roycroft: bang and olufsen sounded great, and won for design hands down, but their gear was all fairly low-powered
01:07 AM miss0r: I actualy still have a crown 850 laying around somewhere (its a PA amp, for 19")
01:07 AM roycroft: harmon-cardon were another great quality brand, but again, lowe powered
01:07 AM roycroft: tandberg made some amazing receivers back then
01:08 AM roycroft: but mid-powered
01:08 AM miss0r: I see you somewhat share my idea of the music needs some volume to be listened properly to
01:08 AM roycroft: the yamaha, mcintosh and crown were the three brands that had high powered amps that sounded great
01:08 AM roycroft: well
01:08 AM roycroft: i don't listen to music really loud all that often
01:08 AM IchGucksLive: CaptHindsight, google search "heidenhain ls 803 datenblatt"
01:08 AM roycroft: but good hifi gear needs to support a very wide dyanmic range
01:08 AM roycroft: dynamic
01:09 AM roycroft: so there needs to be a lot of power for the peaks
01:09 AM roycroft: you can listen to a 40w amp at a given volume level and it's ok
01:09 AM roycroft: but the peaks will be clipped
01:09 AM IchGucksLive: CaptHindsight, www.braunem.de/content/uploads/.../Kompatibilitaetsliste_fuer_Abtasteinheiten.pdf
01:09 AM roycroft: listen to a 100w amp at the same average level and your peaks will come through just fine
01:09 AM roycroft: so yeah
01:09 AM miss0r: I turn the volume up to a point where anything but pure, undistorted sound would be uncomfortable. Then I lean back and close my eyes
01:09 AM IchGucksLive: CaptHindsight, https://content.heidenhain.de/doku/oma_vrz/Oma_Coun/VRZ/700/.../22111291.pdf
01:09 AM roycroft: power is good
01:10 AM roycroft: in the '80s some other brands came out that were pretty nice
01:10 AM IchGucksLive: CaptHindsight, oem are most ML branded
01:10 AM roycroft: denon were a pretty good mid-range brand, for example
01:10 AM roycroft: marantz kind of went downhill in the late '70s
01:10 AM miss0r: That is what I told my self 'power is good', when I build a cabinet for an 18" bass speaker, to use as a subwoofer in my home cinema :) The wife still doesn't understand why :D
01:11 AM roycroft: some of their tube stuff from the '50s and '60s was outstanding
01:11 AM miss0r: denon since then lost it
01:11 AM IchGucksLive: im off E-bikes are fully loaded guests are finishing there Breakfest off we go for a 4hr ride
01:11 AM roycroft: i don't follow hifi gear these days
01:11 AM IchGucksLive: this is the first major forest tour weekend to be
01:12 AM miss0r: Denon is most commonly knows for their $100 wallmart amps/recievers. Listed at 500 watt, but more likely 75
01:12 AM miss0r: "you know the kind"
01:12 AM roycroft: i did find it humorous when hifi snobs went back to tube gear
01:12 AM roycroft: and "disovered" that amps sound better with matched tubes
01:12 AM miss0r: 'back to analog, man' :]
01:13 AM roycroft: because outfits like mcintosh, scott, fisher, marantz were using matched tubes back in the '50s
01:13 AM miss0r: yeah :]
01:13 AM roycroft: somehow, though, this was a major discovery in the '80s
01:14 AM miss0r: meh... Marketing done right
01:14 AM roycroft: anyway
01:14 AM roycroft: there's a lot of great hifi gear round
01:14 AM roycroft: around
01:14 AM roycroft: mcintosh are at the top of the mountain
01:14 AM roycroft: but they share the peak with some other brands
01:15 AM roycroft: i'm happy with what i have
01:15 AM roycroft: other folks are happy with what they have
01:15 AM roycroft: and i'm happy for them
01:16 AM miss0r: I just find myself thinking: If we used the same setup(amp, speakers, cables ect) but swapped out my NAD series 20 with your mcintosh / visa versa, would you be able to hear the difference ?
01:16 AM roycroft: and btw, i bought that preamp for ~$500 in the late '90s
01:16 AM roycroft: i can sell it for $1200 tomorrow
01:16 AM roycroft: maybe
01:16 AM miss0r: but you wouldn't want to ;)
01:16 AM roycroft: maybe not
01:17 AM roycroft: i can sure tell the difference between my mcintosh gear and my hk receiver
01:17 AM roycroft: i've hooked both up to the advents
01:17 AM roycroft: and the hk is a very good receiver
01:17 AM miss0r: In my ignorant mind, it is all about 1:1. The better your equipment, the more the output should look like the input
01:17 AM roycroft: for the most part, yes
01:18 AM miss0r: well, if you don't take acoustics into account ect.
01:18 AM roycroft: one really nice thing about mcintosh amps is that they use output transformers
01:18 AM miss0r: You'll need to explain that to me :)
01:19 AM roycroft: there is never an impedence matching issue
01:19 AM roycroft: plug one set of speakers in
01:19 AM roycroft: plug two sets of speakers in
01:19 AM roycroft: no difference
01:19 AM miss0r: I can see why that is smart :)
01:19 AM roycroft: with a conventional amp if you have two sets of speakers on your impedence drops from 8 ohms to 4 ohms
01:19 AM miss0r: sure
01:19 AM roycroft: with my hk, for example
01:20 AM roycroft: which lives in my garage
01:20 AM roycroft: i have a second set of speakers in my welding shop
01:20 AM roycroft: when i kick in the b speakers
01:20 AM roycroft: the volume drops on the main speakers
01:20 AM roycroft: and they start sounding tinny
01:20 AM roycroft: i have to boost the bass when using both sets simultaneously
01:20 AM roycroft: that's not particular to the hk
01:21 AM miss0r: Nope. alot of amps does that
01:21 AM roycroft: almost all amps do that
01:21 AM roycroft: with the mcintosh
01:21 AM roycroft: i have my stacked advents in my living room
01:21 AM roycroft: and some weatherproof outdoor advents mounted outside on my patio
01:21 AM roycroft: i turn on the outside speakers
01:21 AM roycroft: and the main speakers sound exactly the same
01:21 AM roycroft: no volume difference
01:22 AM roycroft: no frequency curve difference
01:22 AM miss0r: More amp manus. should do this
01:22 AM roycroft: mcintosh are the only vendor who use output transformers
01:22 AM roycroft: and they wind their own transformers by hand in their manufacturing facility
01:22 AM roycroft: just like they've done since 1949
01:23 AM roycroft: so i'd say i would be able to tell a difference in that instance
01:23 AM roycroft: if you kick on a second set of speakers
01:23 AM miss0r: Alright, I can see that ;)
01:23 AM roycroft: but with other amps, you can adjust the volume and equalization after turning on the second set of speakers
01:24 AM roycroft: and they will still sound great
01:24 AM miss0r: Or with my old sony here, that has two seprate output amps build in. :)
01:25 AM * miss0r needs to run out'n get some more ciggarettes
01:27 AM CaptHindsight: smoke and a pancake
01:27 AM roycroft: i have to admit, i really like the look of mcintosh gear
01:27 AM roycroft: the sound is what is most important
01:28 AM roycroft: but given that there are several brands that sound really great, one of them looks the best in my eyes
01:29 AM roycroft: i've designed some greene & greene style cabinets for my pre-amp and tuner
01:29 AM roycroft: i'll be building them soon - they'll be my first real project that i make using the new router table
01:29 AM roycroft: and my first greene & greene style pieces
02:25 AM Deejay: moin
02:30 AM miss0r|office: fragalot: You there man ? :)
03:14 AM fragalot: miss0r|office: hey!
03:19 AM miss0r: Now i'm not at the office anymore fragalot
03:20 AM fragalot: oh. :(
03:20 AM miss0r: And I have to leave for the dentist in 5 minuts :D
03:20 AM fragalot: :)
03:20 AM fragalot: your favorite pass-time
03:20 AM miss0r: But I've found something that might intrest you ;)
03:20 AM fragalot: oh?
03:20 AM miss0r: Right next to me a have a 32mm thick cast iron plate
03:20 AM fragalot: Ooo. What size?
03:21 AM miss0r: 480x915
03:22 AM miss0r: Been aging atleast 30 yeard :]
03:22 AM fragalot: excellent :D
03:22 AM fragalot: a chunk of that would make for a very nice table i'd say
03:22 AM miss0r: It has a few holes in it, and it is slightly warped :) But I'm sure we can make you a nice mill table from it
03:22 AM miss0r: indeed
03:22 AM fragalot: I've ordered all of the alu parts this morning too
03:23 AM miss0r: meh :] I was trying to catch you before you ordered anything
03:23 AM fragalot: that's fine i'm sure I can use the bed plate for something else :P
05:35 AM gloops: got it going yet holzjunkie?
05:36 AM XXCoder: boo
05:36 AM XXCoder: cool https://www.youtube.com/watch?v=GUKoKbmAKcc
05:36 AM XXCoder: nut in nut/
05:37 AM holzjunkie: gloops: the connection is going now the hardware works at the millingcenter will begin
05:37 AM XXCoder: your challenge? nut in nut in nut
05:53 AM gloops: damn this motor looks small, got my doubts it will lift z axis
05:55 AM gloops: supposed to be nema 23 270oz, looks like nema 17 to me
05:56 AM XXCoder: easy enough to find out
05:56 AM XXCoder: is bolt pattern 23mm or 17?
05:56 AM gloops: have to get up and check
05:58 AM gloops: no it is 23, i had an 8 wire 3Nm motor on z with only 4 wires connected - easy strong enough, so i figured i didnt need another 3Nm a 1.9 would suffice
06:01 AM gloops: the mrs got the delivery as well, i really need to show some cutting before i buy much else LOL
06:01 AM XXCoder: lol
06:02 AM XXCoder: make some nice wood sign or something.
06:03 AM gloops: yeah ill make something with a heart in it
06:03 AM gloops: in fact no i wont
06:04 AM XXCoder: lol ok
06:04 AM gloops: and the motor came with pairs twisted together, thats a first
06:06 AM XXCoder: nice
06:06 AM gloops: right may as well get it on, im convinced the 8 wire motor has a bad coil or short, 3 drivers - 2 different types hve acted up only on that axis
06:06 AM XXCoder: https://www.youtube.com/watch?v=GeMqEw6JsZs check this out
06:06 AM gloops: im thinking some kind of feedback is interfering with the driver, from the motor
06:07 AM XXCoder: hard to be sure
06:07 AM XXCoder: never used those 4 pair type
06:08 AM gloops: those chopping boards are nice yes, ive got loads of random hardwood could make some nice ones
06:11 AM XXCoder: yeah
06:11 AM XXCoder: some program can do it
06:11 AM XXCoder: vcarve?
06:12 AM XXCoder: anyway you use some V cutter and cuts board and logo negative
06:12 AM XXCoder: then glue tohgether and cut, then grind top down to match
06:15 AM XXCoder: well time for me to pretend to be dead. later
06:43 AM gloops: right, hope i got the dipswitches right or this could be the fastest nema 23 in the world
06:45 AM gloops: XXCoder v carve can do it, also some free programs, f-engrave does it adequately
06:46 AM gloops: with aspire if you hollowed the board out, you can project 2d drawings onto the 3d form, dont think v carve does that
06:47 AM gloops: for different uses, chopping boards are better either convex or concave
06:58 AM JT-Mobile-: I used f-engrave for that harley sign it came out good
07:01 AM JT-Mobile- is now known as JT-Mobile
07:07 AM gloops: right, something tells me something is wrong with z wiring, new motor out of box wont step properly
07:07 AM gloops: so i need to go through that again
07:07 AM Tom_itx: 43 and declining
07:09 AM gloops: thats new motor and new drivers, still same
07:10 AM Tom_itx: i thought you were off and running with that thing
07:11 AM gloops: it works on 8 wire motor, but...driver occassionally tripping off, i decided to ignore that and carry on, while new 4 wire motor came
07:13 AM gloops: im on it tommorrow anyway, only been having half an hour sessions lately, this is probably simple wiring issue
07:15 AM gloops: one common thing , with every motor and every driver ive tried, the motor makes a kind of oscillating buzzing noise when idle, 3 motors ive tried, they all do it, even when driver is changed, same noise, what could that hint at?
07:15 AM JT-Mobile: 51F in Southaven
07:15 AM JT-Mobile: electrical noise
07:16 AM gloops: well, ive tried ruling out noise, disconnected everything near that motor, no change
07:16 AM gloops: forums seem to suggest underpowered but i cant see how
07:18 AM gloops: ill get multimeter out later and go right through it again, missing something
07:21 AM JT-Mobile: underpower ie voltage too low should not cause a stepper to hum unless it is under a load and not enough power to maintain position
07:21 AM gloops: i see, well it mainly does it when idle, some nice tunes, not that loud but always there
07:21 AM renz: hum like, all the time?
07:21 AM JT-Mobile: what happens when you lift the z a bit with your hand?
07:21 AM gloops: renz yes
07:22 AM renz: can you change it?
07:22 AM gloops: what happens to the motor?
07:22 AM renz: like, lean on the machine or the motor
07:22 AM gloops: ill try it shortly
07:22 AM gloops: lean on the motor what would that do?
07:22 AM renz: if you can change it, its maybe just normal coil vibration plus some resonance in your setup amplifying it
07:23 AM renz: so fix is prob something mechanical
07:23 AM renz: if you cant change it, id guess its just some combination of switching power supply and coil materials
07:23 AM gloops: i dont think its vibration the mounting is solid, ive had 3 motors on it they all do it
07:24 AM renz: like, do they scream or is it just like a low level white noise hiss?
07:24 AM gloops: i thought the psu, but the y motor is on that psu - absolutely fine
07:24 AM FRANK___: hi theree
07:24 AM renz: or are you hearing like, 60 hz mains hum
07:24 AM gloops: hiss yes, when stood
07:24 AM renz: 60 or 120
07:24 AM renz: thats kind of normal
07:24 AM gloops: nah its noticeable, none of the other motors do it
07:24 AM renz: i mean, maybe yours is really bad, but nema23 size stuff will make a noise when powered up
07:25 AM gloops: you know those horror films where you get some wierd voice that you can make out, just a low hissing, humming its like that
07:25 AM renz: same motor?
07:25 AM renz: like, type and spec
07:25 AM gloops: odd time ive heard a hum from the other motors but it goes when they warm up, this is full on as soon as powered up
07:26 AM renz: if theyre something newish and traceable and one of the motors sounds way diff i would call the motor people
07:26 AM gloops: it isnt the motors
07:26 AM renz: you can get it to move across motors?
07:26 AM renz: like, that supply, that axis, any motor?
07:27 AM renz: also if your machine is huge learning on it prob wont do shit, leaning into the noisy motor case might
07:28 AM renz: its a switching supply?
07:29 AM gloops: its a chinese psu
07:29 AM renz: its maybe your psu and your drivers beat frequency
07:29 AM renz: plus normal coil hiss
07:30 AM gloops: what about ground - poor ground or something
07:30 AM renz: like, driver PWM plus slightly variable psu switching frequency, so there would be those plus the sum and diff freq
07:30 AM gloops: ill check it out anyway, slowly eliminating causes
07:31 AM renz: well maybe but this is acoustic, not electrical
07:31 AM renz: so there needs to be a way to make physical vibrations, which is going to be coils
07:32 AM renz: grounding might affect the the way the psu switches
07:32 AM renz: i mean generally you want to ground your shit well
07:33 AM gloops: turning the motor, holding the motor, holding the z plate - no difference
07:33 AM renz: if you can, you star ground all the major subsystems back to the psu ground independently, and avoid loops
07:33 AM renz: same driver as the Y axis?
07:34 AM gloops: its all done, ill just have to check it all again, missing something stupid here i think
07:34 AM gloops: same type of driver
07:34 AM gloops: maybe psu has one bad pin, ill swap those
07:34 AM renz: try holding the screw
07:34 AM gloops: i just have
07:35 AM renz: otherwise, yeah check connections
07:35 AM renz: tug light on wires is usually good for checking bad connections
07:36 AM renz: if performance is what its supposed to be maybe just kind of ignore it
07:37 AM renz: is the machine big?
07:37 AM gloops: it isnt just the noise, the motor wont step properly, the noise is just a common thing ive had on that axis with different motor and drivers, something cross, maybe a splinter of wire or something
07:37 AM renz: oh
07:37 AM renz: yeah
07:38 AM renz: does it skip sometimes or its totally doing junk moves around the same spot?
07:39 AM gloops: sometimes the driver just stops, no lights, switch psu off, back on - fine for another 5 minutes
07:39 AM gloops: but have changed drivers 3 times
07:39 AM renz: there a fuse inline or something?
07:39 AM renz: switch?
07:39 AM gloops: no no fuse
07:40 AM gloops: no switch, its connected exactly the same as the y to the same psu, thats fine
07:40 AM gregcnc_: have you checked out the motor? resistance, shorts
07:40 AM gloops: tried 3 different motors and drivers
07:40 AM renz: three motors same shit
07:41 AM gregcnc_: what's left cables?
07:41 AM renz: heh maybe your burnt all three identically and quickly without a smell
07:41 AM gloops: ill look again anyway, pretty pointless pondering it, need to check everything with tester see whats happening
07:41 AM renz: yeah i think hes kind of on right track
07:41 AM gregcnc_: steppers aren't that critical
07:42 AM renz: does the psu have some sort of enable?
07:42 AM gloops: cables, connections, maybe bad pin on psu, bob
07:42 AM renz: floating enable might do weird shit like that
07:42 AM gloops: noise, i dont know how
07:42 AM renz: on a drive, too
07:43 AM gloops: there is enb on the drivers that i never connected
07:43 AM renz: usually opto stuff, so itd take a crazy noise source at high freq
07:43 AM CaptHindsight: gremlins, then search signs of a witch, steppers are always noisy
07:43 AM renz: yeah but to flip optos you need to get circuit parasitics involved
07:44 AM renz: GHz stuff could do it
07:44 AM renz: i dunno if like, a phone is going to get enough current spinning to light up the coupler, tho
07:44 AM CaptHindsight: older people don't mind steppers since they tend to lose hearing at higher frequencies
07:44 AM renz: haha
07:45 AM renz: yeah the noise is pretty white
07:46 AM gloops: well i was pretty exasperated with this a few weeks ago,thought id cured but didnt, im pretty indifferent to all these snags now, i will sort it, i know how it works now no good getting stressed and no good expecting it to be done in 5 minutes
07:47 AM renz: you need ice cream
07:47 AM CaptHindsight: get better drivers
07:48 AM CaptHindsight: they tend to keep the motors quiet
07:48 AM renz: it sounds like a psu connection or a floating enable signal
07:49 AM gloops: ive tried 2 kinds of drivers, off perfectly working axis, new drivers out of the box lol, its some stupid thing, probably so obvious im not even looking for it
07:49 AM renz: motor noise is just maybe how that axis sounds but the intermittent driver shutdowns isnt normal
07:49 AM CaptHindsight: which drives are these?
07:50 AM gloops: dm542 and tb6600
07:50 AM CaptHindsight: I've never heard a quiet tb6600
07:50 AM gloops: now you have made me think, i blew a driver on that axis by reverse connection +-
07:51 AM gloops: i wonder if that has chogged that psu pin/supply
07:51 AM renz: yeah maybe
07:52 AM gloops: can one psu terminal go bad indepedent?
07:52 AM renz: like possibly there is a burnt resistor or ferrite that doesnt fuckup until its hot
07:52 AM renz: yes
07:52 AM gloops: hmm, thats my first test then when i go back to it
07:52 AM gregcnc_: i thought PSU have been swapped
07:52 AM renz: most likely there would be signs
07:52 AM gloops: check output from that pin
07:53 AM gloops: psu not been changed no, y is running fine from same psu
07:53 AM renz: if its a psu with multiple terminals per output, their probably in parallel
07:53 AM renz: so it would be weird if it was a psu commonent because the other drives would cycles at the same time
07:54 AM renz: but if the terminal has burnt and gone resistive, it will heat up, and thats maybe the time dependent variable
07:54 AM gloops: ill check it out anyway, bbl
07:54 AM renz: like, maybe a trace is burnt and when it heats up the trace lifts enough to break contact
07:55 AM renz: there would be a smell though
07:56 AM renz: prob just a bad connector or cable
07:58 AM Loetmichel: *meh*... chinese manufacturers... just when final mounting 22 All in one PCs we noticed that they forgot a Dsub cutout... and we noticed AFTER powder coating... :-( *modifying the CNC mill* *milling the Dsub in 1mm steel 22 times* ... -> http://www.cyrom.org/palbum/main.php?g2_itemId=17055&g2_imageViewsIndex=1
07:59 AM CaptHindsight: https://www.amazon.com/gp/offer-listing/B0054H4X16/ref=dp_olp_0 us this a replacement for the smoke used in power supplies?
08:00 AM CaptHindsight: Loetmichel: at least you had space for one more
08:01 AM CaptHindsight: I like your spindle reach extender
08:04 AM Loetmichel: CaptHindsight: it was in our drawings... they just forgot to program it.
08:04 AM Loetmichel: so yes, there was room for it
08:08 AM CaptHindsight: typical, if you don't notice or complain then it's job well done
08:09 AM * Loetmichel had the worker come to me yesterday "ahem, Loetmichel: where should i put the fourth Dsub9? there is no hole for it like in the prototype!
08:09 AM Loetmichel: "
08:10 AM Loetmichel: <- "..." [homer-simpson-NOO]
08:20 AM Loetmichel: CaptHindsight: was the only idea i had to get that large box milled
08:20 AM Loetmichel: mount it in front of the mill and extend the spindle out enough
08:30 AM JT-Mobile: see you all tonight
09:19 AM IchGucksLive: hi all
09:25 AM IchGucksLive: till later
09:28 AM Beachbumpete1: Morning folks
09:29 AM Beachbumpete1: beautiful day here in South Florida :)
09:41 AM mtpocketscnc: hi
09:42 AM mtpocketscnc: how's it going
09:42 AM Beachbumpete1: Hey MT :)
09:42 AM Beachbumpete1: thats a great name BTW
09:42 AM Beachbumpete1: few hobbies can empty your pockets like CNC
09:43 AM mtpocketscnc: thanks lol the truth always works ha ha
09:43 AM mtpocketscnc: yes to my wifes dismay
09:48 AM Beachbumpete1: hehe
09:48 AM Beachbumpete1: gotta go setup a shaper BBL
09:48 AM mtpocketscnc: later
10:12 AM Beachbumpete1: any of you guys have retrofit robotic arms?
10:12 AM splud: not a regular here, but looking for news on Archivist. Was a regular on another channel, and he's not been heard from in about 7 weeks. No answer at the phone numbers available for him either.
10:12 AM splud: Anyone have news of him?
10:13 AM Beachbumpete1: hes logged in
10:15 AM sync: yes Beachbumpete1
10:16 AM splud: how recently. Last seen in ##electronics in Mid-Feb. His archive server is down. Suspecting he's been in an accident or worse.
10:16 AM Beachbumpete1: Oh nice what type of arm are you using?
11:24 AM IchGucksLive: hi all
11:24 AM holzjunkie: tah auch
11:24 AM holzjunkie: tach
11:24 AM IchGucksLive: holzjunkie, klasse tag
11:24 AM holzjunkie: IchGucksLive: oh ja
11:25 AM IchGucksLive: morgen noch viel toller
11:27 AM holzjunkie: IchGucksLive: heute erstmal schön den rasen abgeharkt
11:27 AM IchGucksLive: Jac_, buenas noches a Espaa
11:27 AM Jac_: Hi people! I'm from Spain. Sorry by my English is very bad. I'm find a Laser Printer for mark wood, plastics and metal. ...Do you kown one model That run on Linux!
11:27 AM IchGucksLive: holzjunkie, wir fahren mit grossen traktoren
11:28 AM holzjunkie: ich nehm da mein aufsitzmäher oder meinen Intrac
11:28 AM Deejay: IchGucksLive, stell mal bitte dein encoding auf utf8
11:28 AM Loetmichel: Jac_: you mean laser engraver?
11:28 AM Loetmichel: not printer?
11:29 AM Jac_: Engraver ok!
11:29 AM Loetmichel: a laser printer uses toner to transfer it to a surface, you want to mark the material directly?
11:29 AM Loetmichel: how big shall it be?
11:29 AM Jac_: I'm find on Ebay, but nothing work in linux....
11:29 AM Loetmichel: anyone will work with linuxCNC if its controlled by parallel port
11:30 AM IchGucksLive: Jac_, it depends on the connection not on the software
11:30 AM Loetmichel: do you have a link to one you like that "does not work" on linux?
11:30 AM IchGucksLive: Jac_, conexin de impresora antigua "parallel"
11:31 AM IchGucksLive: Deejay, weiat du wo das geht in xchat
11:31 AM IchGucksLive: Deejay, chatzilla wurde ja abgeschaltet
11:31 AM Jac_: The advertirse dont say if the machine run whit a linux drivers...
11:31 AM Deejay: IchGucksLive, leider nein, nutze kein xchat. aber ich sehe bei dir immer kaputte sonderzeichen :/
11:32 AM Deejay: früher war das nicht so
11:32 AM IchGucksLive: Jac_, link towards the ebay
11:33 AM Loetmichel: Jac_: shwo us the link plrease
11:33 AM Loetmichel: show
11:33 AM Loetmichel: please
11:34 AM Jac_: here is one of this: https://www.ebay.es/itm/NEJE-DK-BL-1500MW-USB-Auto-Maquina-Grabadora-Laser-Bluetooth-4-0-CNC-Impresora/201755289181?hash=item2ef98d665d:g:hZcAAOSwxdtapztO
11:34 AM Jac_: Is the first than I find, sure there are much more...
11:35 AM Jac_: ... more models...
11:35 AM IchGucksLive: Jac_, its a simple Bluetooth data transfer
11:35 AM IchGucksLive: you do not need any cnc software at all
11:36 AM Jac_: Ok. but the driver to run whit cups... gimp... etc??
11:36 AM IchGucksLive: Jac_, the Black -white image is given to the engraver
11:36 AM IchGucksLive: then you select coner marc
11:37 AM IchGucksLive: it will show a rectangle you can position and then press go
11:37 AM IchGucksLive: the depth is manualy to controled by a poti
11:39 AM Jac_: For example if I configure the printe that a Epson LX-300 driver... Can I do printer whitout errors?? ...if I conect the engraver machinte to the serial port for example...
11:39 AM Loetmichel: Jac_: thats a classic USB/serial interface with a windows software
11:40 AM Loetmichel: you SHOULD be able to get that running with wine. or else you can send commands directly, if i read that tutorial correctly it uses gcode
11:42 AM Jac_: I'm sorry but I do not want to use any kind of proprietary software.
11:43 AM Loetmichel: Jac_: you dont have to. you can make your own. The usb-serial driver itself is there. just reverse engineer the protocol that gets the laser to move.
11:43 AM fragalot: hey
11:43 AM IchGucksLive: Deejay, geht das jetzt ;-) :O
11:44 AM Loetmichel: joking aside: that laser in your link is 1.5W (optimistically)... forget to ever engrave metal with it.
11:44 AM IchGucksLive: Deejay, was soll ich schreiben
11:44 AM Deejay: schreib doch mal komische französische oder spanische accents ;)
11:44 AM Deejay: oder auch paar umlaute, IchGucksLive
11:45 AM Jac_: You can recommend some engravemnt that you already have and that works directly in Linux, without having to use wine or virtualize that wichoff??
11:45 AM IchGucksLive: Deejay, Je suis juste en dehors de l'exercice
11:45 AM IchGucksLive: Deejay, Löwe Hüjähna
11:46 AM Deejay: ja, sieht bisher gut aus :)
11:46 AM IchGucksLive: Deejay, danke
11:46 AM Deejay: Espana!
11:46 AM Deejay: IchGucksLive, danke fürs umstellen, macht mir weniger augenkrebs auf dauer ;)
11:46 AM IchGucksLive: NP
11:48 AM IchGucksLive: Jac_, we use our own Linuxcnc Mill to engrave
11:48 AM Loetmichel: Jac_: thought about using a cheap 3dprinter and set up a cheap chinese 5W++ laser instead of the hotend?
11:49 AM IchGucksLive: Jac_, https://www.youtube.com/watch?v=PnxBwhehQWE
11:50 AM Jac_: I am looking for something very economical, it is to experience and if it works, I would use it in some occasion to record some logo in my things.
11:50 AM miss0r: Jac_: what are you going to engrave on?
11:52 AM Loetmichel: Jac_: you can also buy such a laser "toy" like in your ebay link and rip out the electronics and put in a reprap(marlin) board. that is fully supported under linux.
11:52 AM Jac_: Plastic materials, wood, or metals...
11:52 AM Loetmichel: and there are tools to convert b/w images to Gcode, too
11:52 AM Loetmichel: open source
11:52 AM Loetmichel: tools
11:52 AM miss0r: I'm no laser wiz, but doesn't it take alot more than 5watts to laser engrave metal?
11:53 AM Loetmichel: but as i said: forget engraving metals with an 1.5W 405nm laser
11:53 AM Loetmichel: will not work
11:53 AM Loetmichel: miss0r: 5W should be able to slowly "mark" (as in discolour) metals
11:53 AM Loetmichel: not cut them of course
11:53 AM miss0r: Loetmichel: I have been considering getting a small laser attachment to put on my desktop cnc.. How much effect would you suggest for engraving steel/alu ?
11:54 AM IchGucksLive: Jac_, below 10W it is a nightmare on metal
11:54 AM Loetmichel: we tested a while ago: you need about 80W Co2 to CUT 0.2mm stainless steel
11:54 AM Jac_: OK, if I dont need more power... I only need that the engraver run perfecty on my favourite Linux distribution... Debian... Ubuntu...
11:54 AM Loetmichel: marking is a lot easier.
11:54 AM miss0r: sure... but what am I looking at? should a 10 or 15watt be enough for proper engraving?
11:55 AM IchGucksLive: Jac_, it will run
11:55 AM Loetmichel: Jac_: as i said: then get that laser, rip out the propetary board and install a reprap (3dprinter) board instead
11:55 AM IchGucksLive: Jac_, i see it even takes grayscale
11:55 AM Loetmichel: then you can use all the 3dprinter tools that come with that
11:55 AM Loetmichel: those 3dprinter boards understand Gcode like linuxCNC does
11:56 AM Loetmichel: so you have your "open standard"
11:57 AM IchGucksLive: Jac_, as loetmich saying iinvestiung 35USD will improve the mashine to your neeed
11:57 AM Jac_: I'm not an electronic user, I only understand a bit of software, I think it would be difficult for me to change the motherboard of the printer or make any changes to the hardware.
11:57 AM IchGucksLive: ok
11:58 AM IchGucksLive: so you got to live with the China standard minimise
11:59 AM fragalot: hey miss0r
11:59 AM IchGucksLive: Jac_, a 45Euro Android tablet will give you a better performence
11:59 AM miss0r: hello fragalot. Haven't left for the mountains yet?
11:59 AM fragalot: just got back to the cabin
11:59 AM fragalot: absolutely miserable outside
12:00 PM miss0r: Yeah, I would know. I'm actualy a scotish Lord
12:00 PM fragalot: didn't expect anything less :P
12:00 PM miss0r: and my wife a lady :]
12:00 PM fragalot: how did your catchment thing go btw?
12:00 PM IchGucksLive: Jac_, the image is the main problem to be generated as the terminal needs it
12:01 PM miss0r: It was our wedding gift from a friend of mine. We each own 1 foot^2 of land at some estate I can't remember the name of.
12:01 PM IchGucksLive: Jac_, https://www.youtube.com/watch?v=27IA3I3zEUM HOW i do
12:01 PM fragalot: haha, nice
12:01 PM miss0r: Yeah. It still had some tweaking needed to be done. but it works :)
12:01 PM miss0r: I took a few more photos, after I installed it: https://imgur.com/a/KBhR4
12:01 PM miss0r: I hope it makes more sense now, what the big idea was
12:02 PM IchGucksLive: Loetmichel, die diode ginge nicht durch den zoll hier
12:02 PM fragalot: haha, looks like a giant baseball glove
12:02 PM miss0r: yeah :]
12:03 PM miss0r: When anybody asks, I tell'em thats where I got my inspiration
12:03 PM miss0r: In reality, this is a coincidence
12:03 PM IchGucksLive: Loetmichel, ich lass das zu einem kolegen nach frankreich liefern der bringt das dann mit
12:05 PM IchGucksLive: im off BBQ time its 15deg outside
12:08 PM Jac_: Thankyou IchGuchksLive... Blender is a greath program... I dont use it... Alwais I use Gimp, but to engravement my name is o record my name in a jpg, or pdf file, and then throw it to the recorder is enough ... I do not need to record grayscale. Thank you very much for your attention and for your time ... Happy Hacking on linuxCNC. Ciao!!!
12:11 PM SpeedEvil is now known as Guest68033
12:27 PM Loetmichel: miss0r: you can start "marking" aluminium and stainless steel at about 5W
12:27 PM Loetmichel: but its painfully slow
12:27 PM Loetmichel: brass is a bit easier
12:27 PM miss0r: so 15watt will be 'acceptable' speed wise?
12:28 PM Loetmichel: i would recommend at least 10, better 20W to be able to mark metals at least somewhat fast
12:29 PM Loetmichel: still painfully slow if you do a large picture as a "pixel art"
12:29 PM Loetmichel: but vector graphics at least are endureable then
12:29 PM miss0r: I wouldn't embark on that :D
12:31 PM Loetmichel: ... and thats said by a man that rapes a CNC 6040 into shape to do steel work outside the bed (and painfully slow,too) ... -> http://www.cyrom.org/palbum/main.php?g2_itemId=17055&g2_imageViewsIndex=1
12:33 PM miss0r: :D
12:33 PM Loetmichel: (the black enclosure hanging in front missed a Dsub cutout... and i have 22 of those at the company. sadly we noticed the missing hole when we wanted to mount the whole PC, so already powder coated... -> punch wasnt an option)
12:34 PM miss0r: *sigh*
12:37 PM Loetmichel: `
12:37 PM Loetmichel: ?
12:38 PM miss0r: I feel your pain there :D
12:51 PM Beachbumpete1: hehehee
12:57 PM Joe_Hildreth: anyone have time for a couple of remedial questions?
12:57 PM fragalot: for questions, sure.
12:58 PM fragalot: answers? maybe, maybe not. :)
12:58 PM Joe_Hildreth: I have been putting together a series of video for LinuxCNC and other than Parallel port and the Hostmot cards, what other hardware is supported for I/O?
12:58 PM fragalot: there are the mesa boards
12:59 PM fragalot: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?LinuxCNC_Supported_Hardware
01:00 PM Joe_Hildreth: I watched a video where a guy compiled LCNC onto a Rasberry PI, using RIP environment. Can LCNC run a machine in this mode, or does it require the realtime extensions?
01:00 PM BitEvil is now known as SpeedEvil
01:01 PM Joe_Hildreth: Thanks, the supported hardware link you gave me will do nicely. :-)
01:01 PM CaptHindsight: preempt_rt
01:01 PM gregcnc_: capthindsight our weather https://www.instagram.com/p/BhOvBstn9OX/
01:01 PM CaptHindsight: pico systems has a few LCNC compatible boards
01:02 PM CaptHindsight: gregcnc_: yeah, just won't quit this year
01:02 PM Joe_Hildreth: Does preempt_rt (Preemptive Realtime??) and real time kernel extensions equate to the same thing?
01:02 PM Beachbumpete1: nice dog
01:02 PM CaptHindsight: https://pico-systems.com/osc2.5/catalog/index.php
01:03 PM CaptHindsight: RTAI is different
01:03 PM Loetmichel: gregcnc_: hrhr. i drove the convertible home from work in "open mode" today
01:03 PM Loetmichel: and i had to use the sunglasses to see the street ;)
01:04 PM Loetmichel: where are you located?
01:04 PM gregcnc_: chicago
01:04 PM gregcnc_: 2°C today
01:04 PM Loetmichel: bitter
01:04 PM Beachbumpete1: ouch
01:05 PM Beachbumpete1: I dont like it when it gets below 50F :)
01:05 PM gregcnc_: -8°C to night, same tmr
01:05 PM Joe_Hildreth: I have used LCNC for a while. But all my experiments have been dedicated PC using PP for I/O. When I make the video, I would like to at least touch on other I/O available.
01:05 PM Beachbumpete1: mesanet FTW
01:06 PM Loetmichel: its about dusk here in germany and still 14.4°C outside
01:06 PM Joe_Hildreth: I am also trying to determine if things like Beaglebone and Rasberry PI are viable solutions or just fringe. Any input on these platforms?
01:06 PM CaptHindsight: gregcnc_: 50's possible by Wednesday
01:07 PM gregcnc_: i hope this is wearing on me
01:10 PM CaptHindsight: all the while permafrost in Siberia is melting
01:13 PM Rab: Joe_Hildreth, I experimented with the BeagleBone Black and Machinekit. I would characterize that as both viable (basically worked), and fringe (Machinekit is a port of LinuxCNC with much missing functionality, BBB is really too slow for AXIS GUI).
01:14 PM CaptHindsight: Rpi --> SPI --> Mesa FPGA --> Mesa IO
01:14 PM Rab: That experience left me feeling that a full desktop PC was the best platform for LinuxCNC.
01:15 PM CaptHindsight: a few different Alwinner ARM boards --> SPI --> Mesa FPGA --> Mesa IO
01:15 PM CaptHindsight: i.MX6 --> PCIe --> Mesa FPGA --> Mesa IO should also work but not tested
01:17 PM CaptHindsight: the Linux distros and toochains for the ARM boards are horrible
01:17 PM pcw_mesa: Also PIDCNC is RPI based
01:17 PM CaptHindsight: someone here wrote a tool to build kernels and a file system without all the cruft
01:20 PM pcw_mesa: we have a RPI/RPI clone I/O daughter-card here (RPI mounts on top) daughter-card = 7C80 (I still need to finish...)
01:20 PM pcw_mesa:
01:21 PM CaptHindsight: https://github.com/NTULINUX/toolchain_builder
01:26 PM pcw_mesa: 6 diff step/dir outs 24 isolated 5-24V inputs 8 isolated 48V 2A outputs spindle encoder, analog spindle interface, RS422/485 port. expansion port single 10..36V power DIN rail mount
01:29 PM CaptHindsight: pcw_mesa: if you do finish, brace yourself for "it doesn't work for me, what am I doing wrong" about eleven thousand times
01:30 PM fragalot: CaptHindsight: that's when you start to sell pre-loaded SD cards :P
01:30 PM * fragalot off
01:30 PM fragalot: cya
01:33 PM -!- #linuxcnc mode set to +v by ChanServ
01:35 PM rmu_: Joe_Hildreth: I'm running linuxcnc on a raspberry pi with mesa 7i80 connected via SPI
01:36 PM rmu_: I would not call it "fringe"
01:37 PM rmu_: just got a Pi3B+
01:41 PM rmu_: actually, it's quite a monster of a machine, x-travel something like 4,5m
01:41 PM CaptHindsight: https://www.nxp.com/products/processors-and-microcontrollers/applications-processors/i.mx-applications-processors/i.mx-8-processors/i.mx-8-family-arm-cortex-a53-cortex-a72-virtualization-vision-3d-graphics-4k-video:i.MX8
01:42 PM enleth: does Pi3 reboot when illuminated by camera flash like the previous ones?
01:42 PM CaptHindsight: i.mx8 might work, i think the dual cores are available up to 800Mhz
01:47 PM CaptHindsight: flash boot feature
01:48 PM rmu_: enleth: of course not
01:51 PM Joe_Hildreth: Thanks Rab
01:52 PM Joe_Hildreth: Thanks rmu_
01:54 PM rmu_ is now known as rmu
01:54 PM Joe_Hildreth: Just to be clear, I didn't mean anything by fringe other than it appears to be outside the norm for installing LCNC. This series I am doing, I want to be fair representation of whats available and its usage.
01:57 PM rmu: the norm probably is PC with parallel port and a breakout-board liek gecko540 driving a 3-axis alu extrusion "käsefräse" as you would call it in german ;-)
01:58 PM rmu: (literally "cheesemill")
02:04 PM Tom_itx: i'm running a 7i90 off a parallel interface which gives much bette performance
02:05 PM Joe_Hildreth: haha, Well I know that my simple gantry based router has served me well even with its severe limitations. It is running on a PC using Parallel Port, BOB and stepper controllers.
02:07 PM Tom_itx: mine is probably 85-90% completely home built
02:07 PM Joe_Hildreth: What I am aiming for is a series of videos that introduce LCNC from a hobbyist point of view. I want to give primitive building blocks that can be applied to any machine. I guess that I just want to take the mystery out of it for new folks.
02:08 PM rmu: what is nice about the pi: it is no problem to get exactly the same hardware again, and you can keep identical spares around
02:08 PM Joe_Hildreth: You have to admit, if you don't come from a *nix environment or machining background and perhaps electronics, then the paradigm shift that has to happen is pretty intense.
02:09 PM rmu: the pi2 and pi3s are powerful enough to run linuxcnc and a GUI with backplot
02:09 PM Tom_itx: i didn't know linux much at all
02:09 PM Tom_itx: it's not for your average walmart shopper, no
02:10 PM Joe_Hildreth: I am intrigued by the PI, I have never really thought about these devices and would but one to do some exepriments with if I knew it could run axis and drive 3 or four steppers and run a small machine.
02:10 PM Joe_Hildreth: I have released the first four videos - https://www.youtube.com/playlist?list=PLaamliiI72ntlrHKIFjh2VjmehRGgZpjm
02:11 PM Joe_Hildreth: Hope I am not violating any policy by giving that URL.
02:11 PM rmu: with rt-preempt kernel, jitter is too high to use the pi to directly generate steps
02:11 PM Joe_Hildreth: So, what is the header on the PI, is it for I/O like an arduino? I am ignorant on this.
02:11 PM rmu: perhaps xenomai pi kernel is better, did not try that yet
02:12 PM Tom_itx: not real current but what i've got: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Mister_plumbing1.jpg
02:12 PM rmu: the header has some I/Os, power, UART, SPI, I²C but no analog in or out
02:12 PM gregcnc_: Tom_itx did you name the machine Mr. Plumbing?
02:13 PM Tom_itx: no
02:13 PM Tom_itx: silly
02:13 PM Joe_Hildreth: Tom, are you using a PC or something else for the controller to run on?
02:14 PM Tom_itx: pc
02:14 PM Tom_itx: that one is using an atom d525
02:14 PM Tom_itx: sitting on the shelf
02:21 PM Joe_Hildreth: rmu, So how is I/O handled in your setup, are you using these pins to a piece of hardware that handles the step generator and drivers, or are you using something else?
02:27 PM CaptHindsight: he said a Mesa fpga card over SPI
02:28 PM CaptHindsight: http://store.mesanet.com/index.php?route=product/product&path=69_62&product_id=291
02:29 PM Joe_Hildreth: Yes he did, I must have overlooked.
02:30 PM Joe_Hildreth: CaptHidsight: thanks for the links. SPI ... Serial Port Interface??
02:30 PM CaptHindsight: we had one of the Allwinner boards with 6+ cores working over Ethernet to Mesa
02:30 PM CaptHindsight: you needed the extra 4 cores for software rendering
02:31 PM CaptHindsight: Joe_Hildreth: SPI bus https://en.wikipedia.org/wiki/Serial_Peripheral_Interface_Bus
02:33 PM Joe_Hildreth: Gotcha, bookmarked so I can read the rest later.
02:33 PM Joe_Hildreth: Well, you guys gave me lots to chew on that's for sure. Thanks for the help with my newbie-esk questions.
02:36 PM Rab: Joe_Hildreth, thanks for undertaking this project.
02:37 PM Joe_Hildreth: I just hope that it helps someone and represents LCNC in a good light.
02:44 PM gloops: what machine is this for Joe_Hildreth
02:45 PM Joe_Hildreth: The video series I am doing isn't targeted to any specific machine. I am trying to give enough primitives so that a user can determine what they may need to set up or build their machine.
02:45 PM Joe_Hildreth: brb
02:50 PM CaptHindsight: gregcnc_: http://www.st.com/content/st_com/en/campaigns/technology-tour-2018/chicago.html
02:54 PM Joe_Hildreth: basically, what is NC/CNC, available controller software, getting LCNC, installing, different I/O options, Stepper Motors, Servos, limit switches, linear slides, homing, touch off, general items or puzzle pieces that someone can use to apply to thier circumstances.
02:55 PM Joe_Hildreth: now admittedly, most of my experience comes from PP, BOB and steppers for gantry routers. Although, if it is popular enough, I would be willing to buy some additional hardware for other things, Mesa Card, VFD, etc
02:56 PM Joe_Hildreth: I want to keep it from and to a home hobbyist perspective. And contructive criticism is welcome!
02:57 PM Tom_itx: imo mesa is for the home hobbyist but can run a multi ton cnc just as well
02:59 PM Joe_Hildreth: When I was looking at the site, there are a HUGE number of boards to choose from. If I elect to do this, I may be back asking what would be the best for a home hobbyist to get.
02:59 PM gloops: hobbyist - parport
03:00 PM Joe_Hildreth: I suspect that the people that I will attract are those who want to make a 3D printer, router or convert a lathe or mill over.
03:00 PM XXCoder: linuxcnc unfortunately cant do 3d printer./
03:00 PM XXCoder: and all of 3d printer firmwares suck on g2 and g3
03:01 PM CaptHindsight: Joe_Hildreth: LPT port or Mesa Ethernet FPGA to a Stepper board like the 7i76
03:01 PM Joe_Hildreth: I wasn't aware that LCNC could not do 3D printer.
03:01 PM Joe_Hildreth: Thanks Cap'n
03:01 PM XXCoder: joe its really just matter of few missing gcodes
03:02 PM CaptHindsight: joe I'm not sure what XXCoder is smoking
03:02 PM XXCoder: CaptHindsight: I don't smoke.
03:02 PM CaptHindsight: most of my LCNC apps are 3d printers, SLS, SLA, FDM , inkjet etc
03:02 PM Joe_Hildreth: doesn't LCNC allow you to create custom codes?
03:03 PM CaptHindsight: Joe_Hildreth: yes
03:04 PM Joe_Hildreth: I also want to talk about things like wiring practice, demonstrate noise with the O-Scope, how to modify thw GUI and stuff like that. Maybe a little ambitious but should be able to do some of these things.
03:05 PM XXCoder: maybe few sub-series, build a problemic machine and "upgrade" with better grounding, with O-scope, so on
03:08 PM Joe_Hildreth: My current machine will serve as a good example of mechanical and electromagnetic noise problems. It was having these issues that made me do research and write the best wiring practices in the docs.
03:08 PM Joe_Hildreth: But you are correct, a hands on demo of a bad example and how to work around and fix it. Great idea.
03:10 PM Joe_Hildreth: If you look at the banner image of my youtube page, you will see why I am having issues with noise. hehehe https://www.youtube.com/c/myheap
03:11 PM XXCoder: joe I like how you display speed up factor
03:12 PM Tom_itx: 3d printer guys are too damn cheap to buy good hardware
03:12 PM XXCoder: reprap specifically. buyt yeah
03:12 PM XXCoder: reprap is all about making as much as possible out of printers
03:14 PM Joe_Hildreth: I would like to build a 3D printer myself, but haven't because for the longest time didn't feel like it was worth the investment. But when using it as a tool for my main hobbies, metacasting and such, it looks like a better deal.
03:15 PM Joe_Hildreth: XXCoder, you must be talking about one of my machining videos. I just started adding the speed up factors to the video.
03:16 PM Joe_Hildreth: I am guessing my YouTube channel is something of the blind leading the deaf. :-D
03:16 PM XXCoder: most stuff you could go cheap but then not everything. some you can fix up afterwards. like lapping cheap chineseium hotend to have smoother bore for better printing
03:16 PM XXCoder: Joe_Hildreth: makes sense since I am literally deaf ;)
03:16 PM XXCoder: so youre literally blind eh ;)
03:17 PM Joe_Hildreth: Well, the old eyes aren't what they used to be!!! Thank goodness for my Geezer Goggle, as my wife calls them.
03:17 PM XXCoder: :)
03:19 PM Joe_Hildreth: I thought I would get a dozen or so done (CNC Videos) them ask the community for some direction.
03:20 PM Joe_Hildreth: Thanks for subbing.
03:20 PM XXCoder: subbed to channel. typically autocaptions works well enough and you could download caption file, fix few words, and maybe fill gap when machining and talking
03:20 PM XXCoder: then upload it
03:21 PM XXCoder: I dont really care if caption is not precisely what you said, just close enough
03:23 PM XXCoder: one of odder facts about captioning I found is that 80% of users is not deaf
03:23 PM XXCoder: one of more interesting channels primitive hobbist he uses captioning to explain stuff, since he never talks in video.
03:24 PM XXCoder: https://www.youtube.com/channel/UCs8DNFOxYen3kuj87aWKG9g
03:26 PM XXCoder: oops wrong channel
03:26 PM XXCoder: this is correct channel https://www.youtube.com/channel/UCAL3JXZSzSm8AlZyD3nQdBA
03:30 PM Joe_Hildreth: I have seen some of his stuff. OK, I will try to figure out the auto caption stuff and caption some of the videos as time permits. I never thought about captions. Thanks for pointing that out. :)
03:32 PM XXCoder: no problem :D
03:32 PM Joe_Hildreth: WOW, I didn't know that YT created subtitles. I just need to figure out how to download them and correct a few things
03:32 PM XXCoder: few years ago I used to call it autocraptons because it was bad
03:32 PM XXCoder: they got it lot better nowdays
03:33 PM XXCoder: lemme find a free tool website a second
03:33 PM CaptHindsight: emclog.archivist.info is down
03:33 PM XXCoder: http://nomorecraptions.com/
03:33 PM XXCoder: thats one with no signup required, free
03:33 PM CaptHindsight: archivist_herron: is still in the channel but archivist has been missing for weeks
03:33 PM XXCoder: few others also free but require sign up
03:34 PM Joe_Hildreth: OK, I see that I can edit in the video manager or download an srt file and edit offline. There I went ... Learned something new today! hahaha
03:35 PM XXCoder: joe oh apparently they require google login now
03:36 PM CaptHindsight: www.collection.archivist.info is also down
03:36 PM XXCoder: yeah have built in editor now forgot about that lol
03:36 PM XXCoder: I captioned only one video, for hearing people. rest is silence
03:37 PM CaptHindsight: http://www.archivist.info all down
03:37 PM hazzy-dev: I hope archivist is ok, somebody was looking for him in devel a few days ago
03:37 PM XXCoder: locally hosted im pretty sure. either hes out of power or something
03:37 PM Joe_Hildreth: Well, this weekend I will see what I can do about cleaning up the captions. I wathed a few minutes of the last CNC video I uploaded and for the most part it done a good job. But I would rather look through them and make sure.
03:38 PM XXCoder: joe thanks again for looking into captions :)
03:39 PM Joe_Hildreth: No Problem, thanks for pointing it out. I suppose when one can hear, they don't think about others who cannot. I would rather have it pointed out to me, then to exclude anyone who can benefit from the information.
03:39 PM CaptHindsight: https://uk.linkedin.com/in/dave-caroline-81038a68
03:47 PM Joe_Hildreth: XXCoder, I think the caption editing tools YT provides will work out fine. I am going through a video now editing.
03:48 PM CaptHindsight: hazzy-dev: been near 2 months now he's been away
03:56 PM XXCoder: Joe_Hildreth: nice. :)
03:56 PM XXCoder: CaptHindsight: that long? thought it was couple weeks
03:57 PM XXCoder: hope hes ok, hes cool guy
04:07 PM gloops: is archivist actually away? i thought he'd blocked me
04:08 PM gloops: i wouldnt blame him for that heh, i asked about him a few times but nobody knew anything
04:08 PM CaptHindsight: been missing and his sites are all down
04:09 PM CaptHindsight: https://goo.gl/maps/JAYSjLNit9q he was somewhere around here
04:09 PM gloops: hmm, he was having some issues with his old op system, but hes still got something connecting to the channel
04:09 PM cradek: have you tried telephoning?
04:10 PM gloops: no number
04:10 PM cradek: there's a number and address in his whois
04:10 PM CaptHindsight: archivist_herron: is still in the channel
04:11 PM gloops: archivist herron - germany
04:12 PM gloops: would he use that
04:12 PM CaptHindsight: I never asked if it was him
04:12 PM gloops: well, i hope hes ok, i dunno im not just saying this, but the last couple of comments i saw him make seemed a bit out character
04:14 PM cradek: CaptHindsight: https://whois.icann.org/en/lookup?name=archivist.info
04:15 PM cradek: no idea if this is up to date (I am pretty sure he doesn't work for that clockmaker anymore) but a call would be a fine thing to try (but be aware it's nighttime there now)
04:16 PM gloops: swadlingcote is only about 30 miles from me
04:19 PM CaptHindsight: the streetview looks similar to his posted house pics
04:19 PM CaptHindsight: but I recall a shed crammed to the roof
04:20 PM gloops: garage is built on to house i think
04:23 PM gloops: well, he is old (i think) lives alone, working on machines using electrics, hes got a big lathe or something in the bedroom bowing the floor
04:24 PM gloops: but i dont think he is like alone/isolated, he has friends and member of societies and stuff, he'll be ok, maybe got a girlfriend
04:26 PM Deejay: gn8
04:27 PM CaptHindsight: Organization: Richards of Burton
04:32 PM gloops: http://www.clock-works.clara.net/
04:55 PM Tom_itx: speculation about ppl on irc is interesting
04:56 PM Tom_itx is now known as Tom_L
04:57 PM CaptHindsight: Tom_L: so you don't think he's was abducted by aliens?
04:58 PM CaptHindsight: he's/he
04:59 PM Tom_L: a while back i left for a weeks vacation and didn't mention it because i didn't want to advertise it. i left the server running so the log would work. i get a call on my return trip from the police saying someone in canada was inquiring about my whereabouts. took me for a min then i realized it was someone on irc getting worried i had died
05:01 PM CaptHindsight: 48 hours in person, 2 months on IRC, I forget what the phone limit is
05:02 PM Tom_L: there were mesages on my machine when i returned too
05:02 PM Tom_L: didn't know anybody cared that much
05:04 PM CaptHindsight: well with Archivist I understand :)
05:04 PM Tom_L: i checked a while back, iirc it was some time in February he last spoke in devel
05:05 PM CaptHindsight: I was planning a trip to the UK was going to see about lunch with him
05:07 PM CaptHindsight: I asked back and I thought somebody he said he was working on some project
05:07 PM CaptHindsight: back then
05:15 PM CaptHindsight: anyone try stmbl yet? https://github.com/rene-dev/stmbl/wiki
05:18 PM pcw_mesa: Andy has and Rene is often on the -dev channel
05:19 PM Tom_L: we got our 10 min of sleet here today
05:21 PM Tom_L: just as i was walking out the door i might add..
05:22 PM CaptHindsight: pcw_mesa: their design isn't it?
05:23 PM pcw_mesa: Tom_L: someone upstairs _doesn't_ like you?
05:23 PM Tom_L: apparently not
05:24 PM CaptHindsight: Smartserial, why did I recall it all being Ethernet?
05:24 PM Tom_L: we need the moisture though so i'm not complaining
05:24 PM pcw_mesa: Yes open source AC servo drive with support for lots of encoder types
05:24 PM CaptHindsight: JT drove an hour east an it's 60's
05:25 PM Tom_L: wonder if he took the bike
05:25 PM CaptHindsight: we're back down to 17F tonight :(
05:25 PM Tom_L: 21 here
05:30 PM CaptHindsight: pcw_mesa: smartserial = 2.5Mbits/sec RS422 signaling?
05:31 PM CaptHindsight: http://linuxcnc.org/docs/html/man/man9/sserial.9.html
05:34 PM CaptHindsight: the Chinese started making RF CO2 lasers for cheap, I checked with Coherent yesterday and their prices nearly match
05:34 PM CaptHindsight: been overpaying for years
05:36 PM pcw_mesa: Yes RS-422 nominally 2.5 MBaud but can run at other speeds (upto maybe 20 MB on FPGAs with a 100 MHz clocklow)
06:06 PM sync: CaptHindsight: source
06:40 PM rene-dev: pcw_home im here as well :D
06:53 PM CaptHindsight: sync: check alibaba, "rf co2 laser"
06:53 PM CaptHindsight: the links keep changing
06:54 PM CaptHindsight: looks like the polyjet patent expires next year in March
07:20 PM CaptHindsight: 100W YAG lasers (1064nm) for $1700
07:35 PM CaptHindsight: SPI Lasers UK Ltd., a subsidiary of the Trumpf Group, has sold its CO₂ laser business to Suzhou Tianhong Laser Co. Ltd
07:36 PM CaptHindsight: sync: you guys sold out :)
07:36 PM CaptHindsight: sync: sorry meant SpeedEvil
07:39 PM roycroft: i wonder what the selling price was
07:40 PM roycroft: could it be ONE MILLION DOLLARS! ?
07:43 PM Crom: ugh... until I figure out the XmuColormapStandardLookup error in 2.8.0-pre1 I'm using Mach3 ugh!
07:44 PM andypugh: Crom: That is an odd sounding error.
07:45 PM Crom: sure is... couldn't find any mention on linuxcnc forums

08:12 PM andypugh: “something like this” followed by an unintelligible compiler command.
08:12 PM CaptHindsight: http://hypernews.slac.stanford.edu/HyperNews/geant4/get/installconfig/996/1.html?inline=-1
08:12 PM andypugh: “Exactly this” would have helped more :-/
08:13 PM andypugh: That’s better.
08:13 PM cradek: is that a compile or runtime error?
08:14 PM cradek: (and what does it actually say?)
08:15 PM CaptHindsight: <-- goes back to his hardware
08:41 PM nallar is now known as Ross
08:49 PM JT-Mobile: mmm crawfish boil tomorrow
09:07 PM Crom: after dinner I'll try that
